Patent IT-1241296-B (IT)
Title: Tensioning apparatus
IPC: B65H/
Filed: 1990-11-23
Granted: 1993-12-29
Abstract: A tensioning apparatus to adjust and control the level of tension in a wire in a winding machine, this has a main rotary tension pulley which applies a tension to the wire, a magnetic brake for applying a braking torque to the main pulley, an auxiliary tension pulley which contacts a part of the wire on the side upstream from the main tension pulley as it is seen in the wire movement direction, a tension bar, pushed so as to rotate, bearing the auxiliary tension roller and pushed in such a way as to rotate in a direction which will stretch the wire, thereby absorbing a variation in the wire tension in a resilient manner, a mechanism for regulating the braking force to adjust the effect of the magnetic brake, and a mechanism for regulating the counter-tension to adjust the force of the spring in such a way as to permit the fine-tuning of the pushing force which acts on the tension bar. The braking force regulation mechanism has a regulating part which is actuated and controlled by a step motor for regulating the braking force. The counter- tension regulating mechanism is also actuated and controlled by a step motor. These motors are controlled by a control circuit so as to maintain a fixed level of tension in the wire during winding. <IMAGE>

Title: Two stroke engine piston ring - is in multiple circular sections to avoid damage when run over ports
Inventor: LAURO M
IPC: F02F/
Filed: 1974-12-02
Granted: 1979-06-20
Abstract: The piston ring (5) is composed of a number of identical circular sectors. Each sector has a cross-section resembling an inverted U. A spring ring (6) fits inside the U and presses the sectors against the wall of the cylinder (3). With conventional piston rings used with two-stroke Diesel engines, there is a tendency for the ends of the ring to project into the cylinder ports as the piston passes them. This is liable to cause damage to the rings and may cause the piston to seize in the bore. A piston ring in separate sectors with an inner spring ring eliminates this source of failure.

Title: Time-resolved differential absorption and photoluminescence electro-optic measurement device
Inventor: ŠČAJEV PATRIK
IPC: G01J3/00
Filed: 2020-07-09
Abstract: The invention belongs to the field of evaluation of recombination lifetime and itsspectral dependences in semiconductor materials for optoelectronics, in particularly, for determination of optically injected, by short laser pulse, carrier density recombination monitoring through their spectral absorption and luminescence changes with time in 200-2000 nm spectral range and with lifetimes larger than 10 ps. For differential absorption regime wide-spectrum emission from halogen or deuterium lamps is focused on the sample and its time-dependent transmission is monitored after pulsed laser excitation with spectral resolution. Transmitted defocusing beam after the sample is collimated and transmitted to an electro-optic deflector with wide-bandgap electro-optic crystal, driven with fast high voltage semiconductor switches with regulated rise-time, deflected signal is focused parallel to the imaging spectrograph slit, in the output imaging spectrograph projects image on sCMOS UV-VIS or InGaAS CCD camera providing spectral resolution horizontally and temporal resolutionvertically, limited to few tens of micrometers and few picoseconds, correspondingly. For time resolved photoluminescence imaging, the sample luminescence is monitored after pulsed laser excitation. Photoluminescence emission from the sample is collimated and transmitted to the same system as for differential transmission to provide the same resolutions.

Abstract: Insulin derivatives of the general formula I <CHEM> and having a charge which is positive compared with the charge of human insulin at neutral pH, can be used to prepare solutions having prolonged insulin action. In the novel insulin derivatives, a basic amino acid has been substituted in the B27-position and/or a neutral amino acid has been inserted in the A4-, A17-, B13- and/or B21-position. The C-terminal of the A-chain, Asn<A21>, may be substituted by another amino acid in order to increase the stability of the solutions at the slightly acidic pH of pharmaceutical solutions. Furthermore, the C-teminal carboxyl group of the B-chain may be blocked with an amido or ester residue. Provided that A21 is Asn, the carboxylic acid group of B30 is free.

Abstract: <PICT:1077999/C2/1> Antibiotic 235A effective against gram negative micro-organisms is produced by cultivating an antibiotic 235A-producing micro-organism of the species Streptomyces Lavendulae or Streptomyces avidinii in an aqueous nutrient medium.  The micro-organism is preferably Streptomyces avidinii MA 833 (NRRL 3077) or Streptomyces lavendulae MA 669 (NRRL 3076). Antibiotic 235A has two components antibiotic 235S and 235L, these are recovered by contacting an aqueous solution containing antibiotic 235A (or a mixture of antibiotics 235L and 235S) with a strongly acid cation exchange resin to absorb a major portion of 235S and a minor proportion of 235L, collecting the effluent and recovering 235L, e.g. by precipitation with ammonium sulphate; eluting the resin adsorbate with dilute ammonia and recovering 235S from the resulting eluate, e.g. by subjecting the eluate to dextran chromatography, eluting with water and recovering 235S and the minor proportion 235L for separate selected eluate fractions or extracting the eluate with n-butyl alcohol and recovering 235S from the resulting extract or dialysing the eluate and recovering 235S from the resulting dialysate, the minor proportion of 235L remaining in the residue.  The antibiotics 235S and 235L may be further purified by reabsorption with a strongly acidic cation exchange resin (235S) and dialysis followed by dextran chromatography (235L).  Antibiotic 235L (Streptavidin) is a crystalline solid m. pt. 223-230 DEG  C. and is a polypeptide containing C 51.1%, H 7.4%, N 16.4%, S 0.2% and O 24.9% of mol. wt. about 60,000 and U.V. absorption maxima at 282 mm  (E1% = 47). Antibiotic 235S has by paper chromatographic procedures been separated into three components, 235S1, 235S2 and 235S3.  Antibiotic 235S2 gives a positive biuret reaction and on acid hydrolysis yields an amino acid product of RF 0.52 in 100 parts n-butanol, 12 parts acetic acid and 100 parts water.  Antibiotic 235S3 is a primary amine, forms salts with acids, is soluble in water, lower alcohols and aqueous acetone, has m. pt. 217 DEG  C., gives a negative biuret reaction and contains C63.1%, H 8.9%, N 13.04%, O 14.96%, mol. wt. 322, possible molecular formula C17H28N3O3, is optically active [a ]25 = +8.5 DEG  (C, 2 in 0.1 N HCl) and [a ]25D = 9.5 (C, 2 in 3.5 NHCl) and has I.R. spectra in mineral oil as shown in the drawing. Antibiotics 235S1, 235S2 and 235S3 are characterized by the property of inhibiting the intracellular synthesis of biotin in gram negative micro-organisms.  The individual components of 235A have no antibiotic activity and thus 235A is composed of a synergistic pair of substances 235S and 235L.

Title: Movement indicator for long-term bed-ridden patient
Inventor: NORDQVIST E G PATRIK
IPC: G01P13/00
Filed: 1986-09-30
Abstract: The housing (1) is closed by a cover, and the outer limiting wall of the channel (2) has a circular cross-section or consists of an equal-sided polygon. In the bottom of the channel may be arranged an inclined ring which presses the ball (3) against the channel outer wall, thus reducing its tendency to move. Specific braking of the ball (3) occurs even when it passes over the angles in the outer wall of the channel (2). Several sensors are evenly distributed along the periphery of the channel, and comprises paired light diodes (5a) and receivers (5b). The ball, in its passage in the channel, breaks the infra-red light beams generated by the light diodes (5a), and this is then recorded by an appropriate registering instrument. The ball is made of soft material e.g. rubber or plastic, enabling it to move as quietly as possible. Electrical sensors may alternatively be used with the ball made of metal, although this creates a noise factor which may be disturb the patients.
